The official cause of death for a husband and wife on Fort Worth vacationing in Fiji remains a mystery after a preliminary finding excludes an infectious disease.
David Paul, a Lockheed Martin engineer, and his wife Michelle died on Memorial Day weekend after both became ill on the South Pacific island.
Michelle died on May 25 after both family members reported being violently ill. David died two days later while waiting for surgery.
The latest findings from the Centers for Disease Control and Prevention, which began earlier this month with an investigation into the couple's death, leaves the family with more questions.
I want the root cause of death, "said Marc Calanog, Michelle Paul's father, to Fort Worth Star Telegram ." If it's not an infectious disease, what is it? "
The remains of the pair are still in Fiji until the outcome of several investigations.
